The US flight was
Southern 242. They attempted to traverse what they thought was a saddle between two cells, but which because of radar attenuation was in reality a level 5 CB. Both engines were corncobbed, the radome was torn from the aircraft and both windshields were smashed, along with associated damage to all leading edges. They actually got the aircraft on the ground, on a rural highway, but they hit a light standard at a gas station with the right wing during the roll-out, and the aircraft veered into the pumps and caught fire.
The ground based radar return and a computer generated weather radar return of what - in all probability - they were looking at in the cockpit at the time they decided to fly that track, along with the CVR and ATC transcripts were part of a weather radar training course I once attended.
